Travelling there: Saudi Arabia has some of the most restrictive travel policies in the world, and advance visas are required for all foreigners desiring to enter. King Khaled International Airport (RUH) serves as the gateway to Riyadh, the capital.
Capital city: Riyadh.
Population: 32.168 million.
Currency: Saudi riyal (SAR).
Climate: Saudi Arabia has a desert climate with extreme heat during the day, and abrupt drops in temperature at night — and low annual rainfall.
Transport: Private cars and taxis are the most popular means of transport especially within cities. There are inter-city bus services as well as domestic flights. Rail travel is quite limited as there are just two train lines across the country. The 4-hour trip between Riyadh and Dammam however is a very picturesque journey winding amongst desert dunes.
Best time to travel: The best time to visit is between November and February when the temperatures are cooler.
What to wear: Dressing is extremely conservative and traditional. Foreign women are required to wear the abaya (long, black cloak), but don't need to cover their hair.
